摘要

高压变频器具有十分明显的节能效果

但其可靠性还不能完全满足发电设备的要求。提出了变频器故障旁路的方法

经在670 t/h锅炉吸风机上实际应用

取得了满意的效果。

Abstract

The high-voltage Frequency converter has obvious energy-saving effect

but its reliability still can not completely satisfy the requirements of power generation equipments.Hence

a method of by-passing the trouble of frequency converter has been put forward

and being used in practice for induced draft fan of a 670 t/h boiler

obtaining satisfactory result.
